For most performers, the last thing they want to do after a concert is to perform again. But not Justin Timberlake, who, fresh from his blistering stage show at Vegas’ Mandalay Bay on Saturday night, headed over to Jet Nightclub at The Mirage for an after-party that rivaled any of his scheduled tour stops.

Soon after JT strode into the club around 1 a.m., the seven-time VMA nominee, along with superstar performer/producer Timbaland, who has been put in charge of the music for next week’s VMAs, gave club-goers a once-in-a-lifetime experience when they launched into their impromptu concert. The hour-long set of the two music icons’ hottest hits had the entire club pulsating into the early morning, when JT and his family and friends made their exit slightly after 4:30 a.m.
